soc: qcom: ubwc: provide no-UBWC configuration 



After the commit 45a29741 ("drm/msm: Use the central UBWC config
database") the MDSS driver errors out if UBWC database didn't provide it
with the UBWC configuration. Make UBWC database return zero data for
MSM8916 / APQ8016, MSM8974 / APQ8074, MSM8226 and MSM8939.
